Talk about GIL is fine, but more importantly if they can reduce the memory footprint of Python by 5x just that would be a great achievement. I also liked their focus on improving cPickle performance, which is an area that badly needs improvement. Basing it on LLVM is a good idea, and if they can remove opcodes nothing like it, since a great lot of time in Python's eval loop is spent in dispatching them. There have been bug fixes and improvements in this, but a lot of them are dependent on new features in GCC. I think they should also take a look at the work already done in Parrot and Cython which can be reused. This line caught my eye: "Apart from these, our benchmark suite includes several crap benchmarks like Richards, PyStone and PyBench", followed by "For charting the long-term performance trend of the project, Unladen Swallow makes use of Google's standard internal performance measurement framework" - I am not sure if the Python community will take kindly to the remark that PyStone is "crappy" ;) Regards > > Shekhar > _______________________________________________ > BangPypers mailing list > BangPypers@python.org > http://mail.python.org/mailman/listinfo/bangpypers > -- -Anand _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
